Swollen Mammary Gland(S) in cats
When to visit the vet?
Urgent see a veterinarian within 24 hours
RED for Fever/apathy, severe Pain, purulent/bloody secretion, ulceration, rapid spread, or if the cat is not eating/drinking. ORANGE remains for firm mammary nodules even without inflammation (promptly), as mammary Tumors in cats are often malignant.

Definition
The term ‘swollen mammary glands’ in cats refers to a noticeable enlargement or Swelling of one or more mammary glands. This change can be due to physiological reasons such as hormonal changes, as well as pathological causes like an infection or a tumor.
Can Occur with the Following Diseases:
Basics and possible causes
A cat’s mammary glands are arranged in pairs and run along the underside of the abdomen. In female cats, they are capable of producing milk to feed their young. The hormonal regulation of these glands is mainly carried out by estrogens and prolactin circulating in the body, which can vary during different life stages of the cat, such as during pregnancy or lactation.
Swelling of the mammary glands can be caused by a variety of factors. A common cause is hormonal changes during heat or after castration / neutering. These hormonal fluctuations can lead to temporary Swelling.
Another possible cause is an infection of the mammary glands, also known as mastitis. This bacterial infection can occur when bacteria enter the gland through small injuries or cracks in the skin. Mastitis is often painful and, if left untreated, can lead to serious complications.
Finally, it is important to consider neoplasia changes. Tumors in the mammary glands, which can be both benign and malignant, are relatively common in cats, especially in older, unneutered cats. These Tumors can lead to visible Swelling and require prompt veterinary evaluation.
Typical accompanying symptoms
- Hardening of the mammary glands: One or more glands feel hard or lumpy to the touch. This can indicate a tumor or significant inflammation.
- Redness and overheating: The skin over the swollen glands may be red and warmer than the surrounding skin, indicating inflammation, such as in mastitis.
- Sensitivity to pain: The cat shows discomfort or Pain when the affected glands are touched. This often occurs during infection processes.
- Discharge: An unusual discharge from the nipples, which can be purulent or bloody, indicates an infection or severe inflammation.
- Behavioral changes: The cat may appear lethargic, lose its appetite, or withdraw due to pain and discomfort.
When to visit the vet?
A visit to the vet should be made immediately if the Swelling of the mammary glands is accompanied by Fever or a general feeling of illness, as this could indicate a systemic infection. A visit is also urgent if the Swelling increases rapidly or the cat is obviously in Pain.
If discharge from the mammary glands is observed, especially if it is bloody or purulent, a veterinary evaluation is necessary to rule out an infection or neoplasia cause. Even if the affected glands appear hard or lumpy, an examination is required to ensure it is not a tumor.
Symptom recognition for animal owners and veterinary diagnostic procedures
To detect swollen mammary glands in your cat, you should regularly feel your cat’s underside for changes. This allows you to detect Swelling, hardening, or unusual sensitivities. Also watch for Behavioral changes that could indicate Pain.
The vet will perform a thorough clinical examination and palpate the affected glands. Based on the examination, they can decide if further diagnostic measures are necessary, such as fine-needle aspiration to take cell samples for cytological examination, or a biopsy to analyze tissue samples.
In addition, blood tests can be performed to identify signs of inflammation or infection in the body. In some cases, diagnostic imaging, such as ultrasound or X-ray, can also be used to more accurately assess the structure of the mammary glands and locate possible Tumors.
What can pet owners do and professional therapy options
If you notice swollen mammary glands on your cat, you should try to gently clean the affected areas, especially if there is discharge. Use a mild antiseptic solution for this to prevent the growth of bacteria.
Make sure your cat stays in a stress-free environment and gets plenty of rest. Avoid unnecessary manipulation of the affected areas to prevent additional Pain or discomfort.
During treatment by the vet, you may be given specific instructions, such as administering antibiotics in the case of a bacterial infection or painkillers to relieve discomfort. Follow these instructions carefully to support your cat’s recovery.
In the long term, castration / neutering female cats can reduce the risk of hormone-related Swelling and the development of Tumors in the mammary glands. Discuss the options with your vet to find the best preventive measure for your cat.
Outlook on current research
Swelling of the mammary glands in cats is an important symptom observed in various contexts, in both healthy and sick animals. A major focus of current research is on distinguishing between benign and malignant processes that can lead to this Swelling. Studies have shown that hormonal changes, especially during puberty or pregnancy, can often lead to temporary Swelling of the mammary glands. These changes are often considered part of the normal physiological cycle.
Another area of research focuses on the role of environmental factors and genetics predispositions. Scientists are investigating the extent to which certain chemicals found in the environment can influence the development of Swelling or Tumors in the mammary glands. This research aims to identify environmental pollutants that could potentially be avoided to reduce the risk for cats.
Molecular biology research has also made great strides. Scientists are researching gene expression in swollen tissue and trying to identify specific biomarkers that could indicate the presence of Tumors. In the future, these biomarkers could help enable early and non-invasive diagnosis, which could significantly improve treatment options.
An interdisciplinary approach is increasingly considered necessary to understand the complex interactions between genetics, the environment, and hormones that can lead to Swelling of the mammary glands. Advances in diagnostic imaging, such as the use of ultrasound and magnetic resonance imaging, offer new ways to better analyze the structure and behavior of swollen tissue.
Research projects dealing with the development of new therapeutic approaches are also underway. This involves investigating how existing treatment approaches such as surgery, chemotherapy, and hormone therapy can be improved or supplemented by new methods. The goal is to improve the prognosis for cats affected by malignant Swelling.
In addition, prevention research plays a crucial role. By examining lifestyle factors such as diet and reproductive behavior, researchers are trying to develop preventive measures that reduce the risk of developing Swelling in the mammary glands. In the long term, this research could help reduce the overall incidence of such symptoms in cats.
There are also significant advances in pharmacological research, where new drugs are being tested that specifically target the molecular mechanisms leading to Swelling of the mammary glands. In the future, these drugs could represent a gentler and more effective treatment option, especially for older cats that may be more sensitive to aggressive treatments.
Overall, research on swollen mammary glands in cats is a dynamic field with many open questions and challenges. Close collaboration between veterinarians, molecular biologists, and environmental scientists is crucial to better understand the complex causes of this symptom and to develop more effective diagnosis and treatment methods.
